frame members 2 which are rigidly attached to the base and secured together beneath the base by a transverse rod or shaft 3.

Adjustably secured on the base 1 is the table t which is secured to the base by means ot' bolts 5 extending through apertures 6 in the table and longitudinal slots 7 in the base to permit the table to be adjusted forward and backward on the base. On the front ofl the table is a downwardly directed tongue or lip S in which is carried an adjusting bolt 9 which has threaded engagement in a ledge 10 on the front of the base and by means of which the table is moved forward and backward.

The table is provided with radially arranged guide ribs 11, 12, 13, and 14 for the jaw blade holders 15 which are provided on one side thereof with a flange 16 adapted to engage beneath the rib adjacent the holder.

Each jaw lade holder comprises a block of metal having an upwardly directed arm 1T ou its inner endj which is provided with a vertical groove 1S opening from the inner end of the block, and adapted to receive the jaw blade 19. The jaw blade 19 is beveled or curved on its inner edge so as to touch the edge ot' each litt or blank 20 of the heel 21. T he jaw blade is secured in the holder' by means ot a bolt 22 which extends therethrough and through an aperture 23 in the holder. rlhe table is provided on its sides with upwardly directed flanges 21 in which are bearings 25 for the adjusting bolts 2G which have engagement in threaded apertures 7 in the jaw holders, and act when rotated to move the jaw holders inwardly and outwardly.

As shown, there are four jaw holders, two on each side of the center of the table. Beneath the two jaw holders on the same side of the table is a wedge plate 28 which bears with its lateral edges against the adjacent edges of the jaw holders, and is provided with a longitudinal slot 29 through which the bolt 5 extends to secure the plate to the table. The plate is provided with a threaded aperture 30 in which is engaged an adjusting bolt 31, similar to the bolt 26, and carried in a bearing 32 in the flange 21. Then the wedge plates are forced inwardly by the bolts 31 they force the flanges 16 of the jaw holders firmly beneath the ribs 11, 12, 13 and 14 and secure the holders firmly in adj usted position. The bolts 9, 26 and 31 each have a groove 33 which seats in the bearing for the bolt and holds the bolt from longitudinal movement. 1f preferred the wedge plate 347 shown in Figs. 8 and 9, may be used in place of the wedge plate 28. The wedge plate 34 has no adjusting bolt but may loe driven into place.

On the rear or inner margin of the table is an upwardly directed flange or breast-rest 19 35 against which the lifts of the heel rest when held in the jaws. The breast-rest is of a. height to accommodate the largest sized heel to be built by the machine.

Supported on the under side of the base 1 by means of bolts 36 and 37 is a bracket 38 adapted to support the nailing mechanism. rihe base is provided beneath the table with an aperture 39, and the bracket is provided with a lug 40 having an aperture 41 in axial 20 alinement with the aperture 39. Mounted for vertical reciprocation in said apertures 39 and 41 is a sleeve 42 which has a flanged collar 43 at its lower end, the flange of which is adapted to rest on the lug 40. A

coil spring 44 is carried on said sleeve and bears at its ends against the base 1 and flange of the collar 43 and normally acts to hold the sleeve at the lower limit of its movement, with its upper end extending into a slot 45 in the table 4.

Rigidly secured in the upper end of the sleeve 42 is the nail holding bushing 46 which has as many longitudinal bores 47 therein as there are nails to be driven into the heel. If the lifts are each made of one piece, only one nail is required; if each lift contains more than one piece, as two or "three, then as many nails are required as there are pieces. As herein shown t-he lifts are formed in one piece and only one nail 48 is required.

A guide rod 49 is mounted for vertical reciprocation in a bearing 50 in the bracket 38. The bearing 50 is below and in axial alinement with the sleeve 42. A. driving rod 51 has threaded co-nnection with the upper end of the guide rod 49 and projects into the lower end of the sleeve 42. On the upper end of the driving rod 51 are the driving pins 52, there being as many pins as there are bores 47 but only one of which is herein shown. When the driving rod is at the lower limit of its movement, as shown in Fig. 1, the driving pins 52 project into the 55 bottom of the bores 47, and the nails 48 seat on the tops thereof1 in said bores.

An arm 53 is formed on the rear of the bracket 38 and extends inwardly above the bracket. The arm 53 is provided with a bearing bracket 54 having vertical slots 55 in its sides. A bearing block 56 is mounted in said bracket and adapted for vertical reciprocation therein. A bell-crank lever 57 is fulcrumed on said block by means of a pin 58. A semi-cylindrical connecting link 59 is pivoted at its lower end 60 to a pin 61 in the guide rod 49, and the other end 62 is pivot-ed to one arm of the bell-crank lever. A foot lever 63 is fulcrumed on a pin 64 in the lower part of the bracket 38, and the upper end of said lever is pivoted to the lower arm of the bell-crank lever by means of a pin 65. The-bracket 38 is provided with a lug 66 against which a lug 67 on the lever 63 strikes when the lower arm of the bellcrank lever and the lever 63 are in axial alinement. A coiled spring 68 is secured at one end to the pin 65 and its other end is secured to any convenient support. Said spring acts to normally hold the nailing mechanism at the lower limit of its movement.

The fiange of the collar 43 has a notch 69 therein which engages rib 70 on the base and holds the sleeve 42 from rotation in the bear- DExtending upwardly from the base, at the rear of the table, is the guide bracket 71 which has a curved guide slot 72 therein, and a guide surface 73 on its front side curved Concentrically with the slot 72. The lower end of said guide surface terminates in a rounded cam or shoulder 74.

Fulcrumed on the rear of the bracket 71 on a pin 75 is a guide lever 76, which has a weight 77 at its rear end and is provided with a longitudinal slot 78 through which the bracket extends. The forward end of the lever 76 is provided with a vertical aperture 79, and the stem 80 of the clamping plate 81 extends through said aperture and is secured in adjusted position therein by means of a set screw engaging in a threaded aperture 82 in an arm 83 on the side of the lever, and bearing against a key 84 carried in an aperture 85 in axial alinement with the aperture 82.

A hand lever 86 is pivoted at 87 to the lever 76 by means of a pin 88 which extends through the slot 72. The lever 86 is provided beneath the pin 88 with a downwardly directed arm 89 which carries a roller 90 adapted to travel on the guide surface 73 and cam 74. The arm 89 is provided with a ledge 91 adapted to abut against the lever' 76 when the clamping plate is thrown out of operative position, as shown in dotted .lines in Fig. 1.

Supported on the front of the frame beneath the base 1 is the paste tank 92 adapted to contain paste in which the heel lifts are immersed before they are put in the machine. The base is provided wit-h a forwardlyand downwardly inclined surface 93 adapted to carry the paste which drips from the heel back to the tank. Supported on the tank and on one of the supporting arms 94 for the tank is the heel gage 95 adapted to gage the height of the heels.

The operat-ion of the construction shown is as follows: A metal templetof the size and shape of the smallest or so called top lift of the heel, having an aperture in it of a size to admit the guide sleeve 42, is placed on the table and the foot lever is operated until it strikes the lug 66, thereby causing the sleeve to enter the aperture in the templet. The table is then adjusted by means of the bolt 9 until the breast-rest 35 contacts with the breast of the templet. The jaw holders l5 having jaw blades 19 therein of a shape to conform to the heel to be built are then moved inwardly by their adjusting screws until the jaw blade holders touch the tcmplet, and the wedge plates are forced inwardly to secure the jaw holders in place. The templet is then removed and the bolts tightened to hold the table rigidly in place. ln adjusting the table the bolts 5 and 9 and the sleeve 42 act as guides to hold the table in proper position. The foot lever is then returned to normal posit-ion, thereby retracting the top of the sleeve to the level of the top of the table and the nail or nails are placed in the bushing 46, the smallest or top lift is then placed on the table between the jaws and the breast-rest and the next lift is immersed in the paste and placed thereon and so on until the proper height for the heel is obtained. During this operation the hand lever 86 and guide lever 76 are turned up to the position shown in dotted lines of Fig. l and the weight 77 holds them in that position with the clamping plate Sl out of the way. After all of the lifts have been put in place the hand lever is pulled downwardly with its roller 90 traveling on the guide surface 73 thereby carrying the clamping plate downwardly to the heel. As the roller 90 passes, beneath the cam surface 74 it forces the clamping plate firmly down on the heel and holds it in that position. As the clamping plate presses downwardly on the lifts the jaw blades force them rearwardly until their breasts touch the breastrest and forms a. straight breast on the heel. iVhile the lifts are held in that position the foot lever is swung rearwardly causing the bell-crank lever 5T to raise the driving rod and driving pin or pins upwardly to force the nail or nails into the heel. The nailing operation is 4completed when the foot lever has reached the limit of its movement. The hand lever is then turned upwardly to carry the clamping plate out of operative position, and when the foot lever is forced to the limit of its movement the guide rod 49 contacts with the sleeve 42 and forces its upper end above the surface of the, table, as shown in Fig. 13, thereby releasing the heel from the jaws. iVhen the foot lever is released the springs ist and 68 return the nailing mechanism to normal position.

iVhen it is desired to build a heel of another size the jaws are adjusted to a templet corresponding to that size of heel. The clamping plate may be adjusted in the lever T6 to accommodate it to heels of various heights.

-is shown in Figs. l0 and l1, the holes l5 are provided with outwardly proj ecting lugs (shown on the left of said figures) which lugs directly engage the metal templet when the machine is heilig adjusted, which lugs also engage the Vlowermost lifts, leaving the jaw plates to engage only those lifts above the lugs.

iiyhile but one specific embodiment of the invention has been herein shown and described it will be understood that many detailsl of the construction shown may be varied or omitted without departing from the scope of the claims.
